APPARATUS FOR IMPREGNATING LIQUIDS WITH GASES.

* Application filed June 4, 1910. serial No. 565,019. g f

To all whom it may concem:

Be it known that I, MAX PASGHKA, a subject of the Emperor ofAustria-Hungary, at Vienna VI, in Austria-Hungary,

have-invented a. certain new and useful Apparatus for ImpregnatingLiquids with Gases, tion.

This invention relates to apparatus for impregnating liquids with gases,and more particularly to a device for mechanically combiningcarbondioxid with water,for bathing purposes.

The main object of this invention is to provide a device of the classdescribed which will combine carbon-dioxid with ,water to the greatestpossible degree. I A further object of this invention is to of which thefollowing is a specifica- 'have the device so arranged that it can bemanufactured at a very low cost, and such that its construction will beassimple as possible in order to eliminate, as far as possible, anydisarrangement in its parts for ordinary usage. 4

Astill further object is to have the apparatus arranged so that the samewill be light, compact, .and easily transportable, and further easilyinstallable.

Other objects of this invention will become apparent as it is more fullyset forth.

I The particular apparatus in question includes a casingcontaining anysuitable porous material, such as glass-wool, wood- -wool, slag-wool,sponge,

or woven plaited and knit fabrics of cotton, 'wool, flax, jute, straw,asbestos, horsehair, and other fibrous and filamentary. materials orsubstances. ,I prefer to use some material after it has been split, cutor shaved so as to provide a fibrous mass having innumerable sharppoints and cutting edges and so arranged as to'permit the liquid and gasto readily pass there through. Liquid and gas connections are made atthe same end of the casing and contiguous tov the spongy mass containedtherein. 7 Y

of this invention, "Figure 1 represents a section'al elevation of adevice embodying this invention. Fig. 2 is a similar view of amodification hereinafter spehifically referred to.

In the construction shown in Fig. 1, 1 represents a casing or conduithaving ascreen or perforated plate 2 connected to one end thereof.Connected to the other end portion of the casing 1 is a chamber 3 havingone side thereof provided with an opening therein, in order to permit agas pipe 4 to extend therethrough, as is clearly shown in ,the drawings.A rose or sprinkler head 5 is connected to the end of the gas pipe so asto. spray the gases into the casing 1. The up per portion of the rose iscon cal, as shown. A cap 6 is. threaded on to the chamber 3, and isprovided with an opening 6* therein,

in order to permlt aliquid pipe (not shown) to be connected thereto.

7 is a mass of shavings, which are ar. ranged so as to permit the fluidsto pass readily therethrough and yetat the same time break the same intoan extremely finely divided state, and cause the same to thoroughlymechanically combine with one another. When this combination hasproperly taken place, the liquid will be saturated with the gas to amaximum degree. It is of course understood. that the length of thecasing 1 is sufiicient to restrain and mix the fluids so that they willbe sufficiently combined.

' In the construction which is shown in Fig. 2, 17 17 17 and 17 d arethe casings used in connection with the apparatus, andwhich are filledwith the porous material 16 and are joined together by ineans of theelbows 18", 18? and 18. The first casing 17* is attached to the chamber19 into which the liquid is forced through a pipe 21, and the gasthrough the pipe 2( against rose 22. The last mentioned casing 17, isprovided with a perforated plate 23 in order to prevent the porousmaterial from being driven, out of the device. rious casings and partsof this device can be readily disconnected wherever desired, so thatthey may be inspected, and the mate'- rial 'therein renewed wheneverneee mary.

It will be noted that the va- While other screens are not shown in thecasings, particularly. those indicated by the reference characters 8 and8', 17*, 17 17 in Order to keep the and 17, it is of course understoodthat the samemay be used at the ends of the casings porous materialproperly positioned within the same. However,

under ordinary conditions, such screens are vided, is in order to enablethe casings to be I provided with different porous materials in thevarious casings, in order to bring about the special resultsadvantageous to special conditions, as well as to keep the device ascompact as possible, particularly where a comparatively long passage ofporous material shouldbe interposed between the inlet periments haveproven that this device will and outlet.

The operation of the apparatus is as follows :The liquid flows into thecasing together with the sprayed gas, and there absorbs a slight amountof-the same. This action is particularly accentuated when the liquidinlet is disposed above the rose on the gas pipe, as the liquid iscaused to flow aroundthe same and mingle with the gas trying to expandand pass through it. As the liquid and gas continue through the easingproper, and 'there engage with the spongy mass of shavings, they arethrown into all directions and caused to intermingle continuously withone another. At the same time, the sharp edges of the porous materialcut the liquid into the finest particles and make the combination morecomplete, and yet at the same time the shavings donot offer a. verygreat resistance to the passage of the fluids therethrough. It will alsobe noticed that the liquid and gas flow in the same direction so thatthey do not obstruct one another in any way but combine while flowing inthe same direction, and thereby provide a more positive intermlnglingthan any other arrangement would provide, mainly because the gas andliquid are kept longer incompany with one another, there- -by giving theliquid more opportunity to absorb the gas.

It is obvious that the process of impregnating the liquid or liquidsintroduced into the apparatus 'inquestion has several independentactions. These actions n ot only serve to mechanically intermingle thegases and liquids, but force the latter to absorb the formercontinuously, thereby making the impregnation as perfect as possible.Ex-

ordinarily' cause one liter of water to absorb from 1300 to 1800centimeters of carbon dioxid C0 The first action consists in introducingthe liquid and gas into a preliminary chamber of the device, so thatthey will be roughly mechanically mixed together. The next actionconsists in causing the liquid and gas to move in every direction, so asto more thoroughly mix together, and at the same time means are providedfor cutting the particles so that the same will be divided into anextremely fine state. The action is further emphasized by reason of thepressure of the incoming fluids. Further the fluids are kept incontlnuous contact with one another for a comparatively long time, sothat a thorough 'absorptiomaction will take place in addition to themechanical intermingling referred to. It will be noticed that thedivision of the fluid particles will be continued so' that eventuallytheir size will be practically "infinitesimal, which makes theimpregnation necessarily very thorough.

The gas is so-thoroughly united with the liquid that separation of thegas therefrom takes place veryslowly even when left standing for alengthy period in a chamber under ordinary atmospheric pressure. This isso even when the impregnated liquid is thoroughly shaken. The liquid isso thoroughly'impregnated by the device, that the amount of gasnecessary for a certain amount of liquid is comparatively small, mainlybecause it is so perfectly combined with the liquid, and,also becausepractically none of the gas can escape without mixing with the liquid.This keeps down the cost of operation of the device, in the firstinstance, and also reduces the-quantity of impregnated fluid necessaryduring bathing,

as the same will remain fully charged during the ordinary time of usage.

It is to be particularly noted that the rear conical wall of the rosefaces the water inlet and extends close to the wall of the casing withthe face of the rose lying next to the porous mass, whereby the rosewill-force the water to pass around it as a film which will envelopbeing thus produced, as they together flow through the porous mass inthe casing.

What I claim as'my invention and desire to secure by Letters Patent ofthe United States is A device for use in impregnating liquids withgases, comprising a casing, a porous mass contained within the casing,the casing being provided at qne end with a water inlet opening andbetween said opening'and the porous mass with a gas inlet opening and agas inlet pipe extendin into the casing through the second name openingand provided within the casin rear conical wall of whic faces the waterinlet opening and extends nearly to the wall I the gas issuing from therose, an 'lntlmate commingling of the gas and water with a rose, the
